I have a half lb of 65% beads in my large coolador but the hygro always shows 70%. Lately I've heen having some wrappers split within a few minutes of lighting up. For me, too high RH would cause wrappers to bust. Which do I believe, the hygro (70%) or the beads (65%). I think I'm going to let things dry out a little. I've got around 15 full boxes at stake in this cooler. BWA? Anyone?
